It really is bullshit because you are holding bullshit coins. Not all the time, holding is applicable. There are coins worth holding for, and there are not. Sometimes there is no problem with the coins, the problem sometimes is us. You must have dump them earlier. If I do not see any practical changes on coins in half or 1 year and risk on other promising coins. Learn what and when to decide.
Indeed, there are three separate coins that simply did not give rise, but this does not mean that you do not need to keep it. There are many examples when people become millionaires.
